I have a PDF or Image . in this i can write something, draw line , high light sentences then download it .
how to Achieve this.
thanks in advance
Well PDF and Images are two different things.
I know it's poor advice but you should really do a quick web search for ".net pdf library". You will find dozens of paid and free code libraries for creating and manipulating PDF documents with plenty of very good documentation on how to use them.
Similarly for Images there are also many, many .net libraries for doing image manipulation.

I'm new to web development and I've been working with this for quite a while now. I'm using wordpress and I need help on doing a multi step survey on wordpress like this one.
sample
Thank you guys !
You can use plugins, I do a search but not find out any multiple steps form jQuery for WordPress.
Here is Contact form 7 Multiple step plugin:
https://wordpress.org/plugins/contact-form-7-multi-step-module/
And here is the demo: http://webheadcoder.com/contact-form-7-multi-step-form/
It's not jQuery multiple steps form for a fast transfer movement, but you can use it for your survey purpose.
Contact form 7 itself does not save submitted data to database, but you can find an extension to do it: https://wordpress.org/plugins/contact-form-7-to-database-extension/
This is to help you get the survey data from use and analyze it.
I hope that helps.

Is it possible to scrape data automatically from websites that require a validation code each time a webpage is accessed? Such as the case when the website shows you a picture of the code and asks you to enter what is shown in the picture. I'm using the rvest package. Is this possible to do?
What you're trying to do is beat CAPTCHAs. That's possible but very hard. This is a spammer's hardest job - to come up with an algorithm smart enough to fill out those fields correctly. It's not something you're supposed to do, the whole point of those validation codes is to prevent access from non-humans. If you're smart and motivated enough to figure out how to answer those questions programatically, you can probably make more money doing that than whatever you're trying to do :)
Some websites offer a direct API, which is the way you're supposed to interact with their data. But getting past a CAPTCHA by scraping is not an easy deed.

How can Prevent copying my Site templates such as CSS & Javascript code or anyone fails to copy my website.
please help me.
I tried many ways but it was inconclusive.I'm sorry that asked this question.There is no way for this problem.I realized my mistake.
Sorry to say but all client-side code can be copied.
Your best bet is to stop publishing your site online.
Obfuscate
However, there are tools that help you obfuscate code. Here's one.

On the other hand, most techniques employ that minify your code.

I am new to dart and really like the editor, I mean, just at the editing features: auto-completion, function signature prompt, etc.
Is the underlining technology totally Eclipse? I am not familiar with Eclipse, but I wonder if Dart editor open source? Is it programmed in C++, Java or Dart?
I guess my question is - is it available relatively easy to grab used for an editor in my application? My application is to be done in Dart hopefully.
Right at the top AND bottom of https://www.dartlang.org/tools/editor/, which is the first search result on Google and DuckDuckGo, it says open-source. There's even a link to all the source code on Google Code. It appears to be mostly Python.
Before asking a question, make some effort to find things out for yourself.

There are tons of resources on how to program using the APIs of various widget toolkits but I can't seem to find much in the way of a tutorial on how to create widget toolkits themselves or how they work n detail. They are basically just black boxes to me right now.
There is some info on QT:
http://qt-project.org/wiki/Category:QtInternals
but it seems quite specific to QT and not geared towards general theory.
Could anyone point me to some resources?
Thanks for reading
There are powerpoint presentaion slides on the following link:
http://aplcenmp.apl.jhu.edu/~davids/605741/handouts/6_SWT_Programming.pdf
Also you may have a look on pdf given on the following link:
http://www.loria.fr/~dutech/DDZ/SWT.pdf
It would have been great to know which programming language you are using (or you'll use) to develop widgets.
Anyways,there is a link which shows the basic concepts behind widgets and also their creation:
http://star.pst.qub.ac.uk/idl/Widget_Programming_Concepts.html
Go through the tutorial/description to see if it meets your need.
Hope it'll help you.
